Remote Access / Virtual Private Network (VPN) Explanation

greetings from saver consulting we're coming to you today just to talk about some of the things we've been hearing from people from friends from customers in the community etc about how do I work from home how do I allow my employees work from home maybe you're the business owner who is just trying to figure this out you know for the first time or maybe you're an IT and you're not exactly sure what to do the concept I want to talk about today is virtual private network or VPN and basically what this means you know a VPN extends your private network which in this case is your workplace across the public network the internet you know into your home so that way you can be at home and you can you know access files that you have at work you can access resources that you and your co-workers are using that you need to get your job done while you're while you're quarantined or while you're you know just not at work there's a few considerations challenges hurdles etc that we need to discuss the first one I want to talk about is your office and remote downlink uplink rates then we're going to get into split tunneling and a couple other things so let's draw this out so this is my office or my you know my corporate headquarters whatever it might be and then over here we'll draw on my house my home and then we also have the Internet okay and so each of these locations has their own internet connection they have their own data rates you know we'll use one of our customers for example they have a 400 Meg downlink and a 20 Meg uplink and then we'll use you know just my home for example and I think I have around 150 down and I believe I have 10 up so if our employee of this business and I was trying to work from home I would have particular concerns and the reason for that is well we have a 20 Meg uplink here at the office and the reason this comes into play is because if I access the corporate network through VPN or even some other method but if I access the corporate network and I need a download files that I'm working on or I need to you know download a database that I'm working on or whatever it might be the corporate network is constrained by this 20 Meg limit so what that means is if I'm trying to get a file from there well we can the file is here so we just follow the arrows back to my house and we see the constraint being this 20 Meg on on the office and 150 at my house so I'm not really worried once it gets to the internet and then goes to my home but I am worried leaving the office it's gonna take a while not to mention the fact that there's probably other people in other homes who are working you know their home they're working from home as well and that you know you get enough people working from home who are all trying to access files and all of a sudden this 20 men comes a real bottleneck the other challenge is there might be people already at the office or there might be processes or services or things going on at the office where they need to be able to push things Center as well maybe your office backs up stuff to the cloud you know maybe use AWS or GCP or is your and they're backing things up there so this can be a real problem you know excuse me where if you have you know a limited uplink and you have a lot of people working off-site there can be some real constraints however one thing that will help you with these constraints is a concept known as split tunneling so if you have a VPN connection excuse me from your home back to your office you don't have to funnel all the traffic back to the office so a split tunneling what it allows you to do is if you're at home and you're trying to access a file from your office location if your VPN service will will know that okay that file is coming from here and it will serve it from there and that's fine but if your VPN service is set up using split tunneling then it will know that the music your streaming or the Netflix you're watching or whatever it might be does not need to go through the corporate network and instead that just interacts directly with the internet and so the split tunnel basically says any traffic that is destined to or from my office go through the VPN connection but any traffic that is destined only for the Internet to and from the internet go directly to and from the internet so then the final thing is and this may be more for the the corporate IT staff is just how do you implement corporate VPN and so basically you know you have a few choices so many of your firewalls have a VPN service on the box some brands such as Palo Alto SonicWALL moeraki juniper Cisco Ford Annette and others all have VPN services on their box you may need to configure them but they are there other other ways you can set up VPN is there are VPN appliances like dedicated appliances you would put in your corporate network such as pulse secure there in most of the fortune 500 companies and they are very secure and they help you manage your you know your remote access and other things as well finally if you don't have if you don't have a firewall that has an only box service or you don't have a pull secure type of VPN appliance you may look at what is known as Windows remote access server so if you have a Windows server in your environment this is a feature that you can that you can set up excuse me that will allow you to manage remote access through VPN using Windows remote access server so thank you for your time today thank you for listening to this if you've made it this far then then I appreciate it but we just want to let you all know that there this is a surmountable problem if you have a need for remote access in your corporate environment it can be done there are some considerations you need to take into mind but it can be done and we are here to help you if you need help but otherwise there's great resources available online and in through any of the manufacturers of your firewalls etc you can reach out to them they
